Intro: Here’s what you need to know from ENDURE24 READING | Training for TDS at UTMB vlog series | Ep 3 by Run4Adventure. The video offers solid insights — we’re pulling out the key takeaways so you can try this workout yourself. The full video has all the details worth watching.

Key Points

• Looped endurance – The race consists of an 8 km (5‑mile) loop across mixed terrain with several sharp climbs. Lou runs this loop repeatedly over 24 hours, aiming for 80 mi (≈ 130 km).
• Run‑walk strategy – Early on, Lou hit fast splits (43 min), then shifted into a “run‑easy‑walk” cadence to keep heart rate controlled, spare the muscles, and stay fresh for the duration.
• Nutrition & hydration – Aid stations throughout offer frequent refills and fuel—Morton gels and bars (about 220 kcal each) mixed with whole foods like pizza and gummy bears to maintain stable energy.
• Gear checklist – Fenix HM65R‑T head‑torch, waterproof jacket, reusable cup, 750 ml water, spare shoes, Salomon Adv Skin 12 vest, and a massage gun for recovery.
• Mental tricks – Think of 24 hours as multiple short loops, not one long slog. Use crowd energy, music, and “reset” breaks every 12–14 mi to stay sharp mentally.

Workout Example (tweak it for your own level):

1. Warm‑up – 10 min easy jog with dynamic stretches.
2. Loop – Run 8 km at a relaxed pace (about 65 % max HR).
3. Break – Walk the steepest climb after each loop, top up your water, grab a bite (gel, gummy bears, whatever).
4. Repeat – Keep doing more 8 km laps.
5. Long‑run goal – Try to hit 60 mi (≈ 96 km) in your first 12 hours, then stick with the same rhythm for the back half.
6. Night running – Drop to a dimmer head‑torch once evening sets in; keep the pace controlled and slow to protect night vision and save energy.

Practical Tips to Try Today

• Scout out an 8 km loop or a park circuit and run it 3–4 times, switching between 5 min run and 2 min walk on the hills.
• Pack a small water bottle and portable fuel; practice refueling at a station along the way.
• Test a head‑torch when it gets dark before committing to a full night run.
• Track your loop times and heart rate; try to stay in your “easy” zone (roughly 1.3 × resting HR).

Closing Note: Give the Endure 24 loop a try, adjust the distance and pace based on what suits you, and log it in the Pacing app to refine your training for the big UTMB TDS push. Good luck out there!
